REGISTERING MECE JANISM FOR lNARFlNGdWACHINES.

SPECIFICATION forming part of Letters Patent No. 595,907, dated December 21, 1897.

Application filed August 16,1897. Serial No. 648,346. (No model.)

To all whom it may concern:

Be it known that I, RUSSELL IV. EATON, of Brunswick, county of Cumberland, and State of Maine, have invented an Improvement in Registering Mechanism for lVarping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a warping-machine with registering mechanism whereby the number of breaks in a set of yarn may be automatically registered and preserved, for when the yarn breaks frequently in a set it implies a fault in the production of the yarn which must be remedied, and it is only by keeping track of the breaks that proper check can be kept on the spinning, &c., preparatory to running the yarn or thread through the warper.

VVarpers as now built commonly have what is called a rise-roll, and immediately after the breaking of a yarn or thread the falling of a suitable drop-wire which was supported by said broken thread effects the stopping of the warper and the rise-roll rises to take up the slack in the unbroken threads of the warp and prevent them from being snarled.

Figure 1, in side elevation, represents a suf- 3o ficient portion of awell-known form of warper with my improvements added to enable my invention to be understood. Fig. 2 is a partial front elevation thereof; and Fig. 3 is a section taken through the line 00 at, Fig. 2.

The framework A, the roll a over which the set of warps of yarn or thread passes on its way from the usual reel 1), the drop-wire c, and the rise-roll d are and may be all as common in warping-machines now in daily use, said rise-roll being allowed to rise whenever a yarn or thread of the set breaks.

Upon a part of the frame A, I attach by suitable screws, as c, Fig. 1, an arm f, having at its upper end a suitable case, as f, it form- 5 ing part of a registering mechanism to be described. This case has mounted in it a suitable stud g, upon one end of which is fixed a toothed gear h and upon the other end a pointer 2', the said pointer being surrounded 5o loosely by a suitable dial on, said dial being marked to designate the number of steps of movement of the hand 'i. This dial is located between the toothed gear 7L and the hand i and is in this instance of my invention sta tionary.

The case f has, as herein shown, a glass face The part f of the armf has mounted in it a shaft 92, provided at its front end with a ratchet toothed wheel a and at its rear with a pinion 173, said pinion engaging the teeth of the toothed gear h, before described.

The rise-roll d is mounted at each end in like manner in a suitable bar 0, which may be lifted by any usual strap and weight 0 0 The upper end of this bar 0 carries a pawl 0 the inner side of which is kept pressed by a suitable spring 0 against a lug 0 so that said pawl when the rise-roll d rises after a yarn or thread of the set is broken will meet and move said ratchet-wheel one step, causing the pinion n acting 011 the gear h, to turn the hand i one step over the stationary dial m, and the number of steps that the said hand turns will be indicative of the number of times the yarn or thread of that set broke when going through the warping-machine.

The ratchet-wheel may be readily turned by hand when the rise-roll is down in working position to thus put the pointer back into its starting position.

This apparatus is especially desirable and reliable for the purpose intended, for the reason that the rise-roll comes but once to the top of the guide between the time that a yarn or thread. of the set breaks and the said yarn or thread is pieced or spliced and the machine again started-that is, the operator in attempting to mend the broken thread may of necessity start and stop the main pulley and shaft and all other parts of the warping-machine more than once. The rise-roll after being brought down by the strain of the yarn through the starting of the machine does not thereafter rise to a point sufficiently high to operate the registering mechanism until the warper has been fully started at regular speed and another thread has broken and brought the machine suddenly to a stop.

I have herein shown a very simple form of registering mechanism which is well adapted for the purpose intended; but it is obvious said registering mechanism to actuate the lat ter a step at each rise of the rise-roll, substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RUSSELL \V. EATON.
